4. A removable brush for a suction cleaner agitator comprising an elongated rigid back, bristles mounted therein and extended from the side thereof, and a resilient seat-contacting member on the bristle-side of said back.

5. A removable brush for a suction cleaner agitator comprising an elongated rigid back, bristles mounted therein and extended from one side thereof, a recess in said back adjacent said bristles, and a block of resilient material seated in said recess.

6. A removable brush for a suction cleaner agitator comprising an elongated rigid back, bristles mounted therein, a rubber block mounted at one end of said back, and means positively to lock said back to a brush seat at the opposite end of said seat.

7. A removable brush for a suction cleaner agitator comprising an elongated rigid back, bristles mounted therein and extended at one side thereof, a rubber block mounted at one end of said back, and securing means at the opposite end of said back to secure said back to a brush seat.

8. In a suction cleaner agitator, a body formed with a brush seat, a brush seated in said seat and comprising a back and bristles, said back being formed with outwardly flaring shoulders on its sides in contact with said body to limit the extension of said back into said seat, and means urging said shoulders against said body.

9. In a suction cleaner agitator, a body formed with an agitating element seat, a surface-contacting agitating element in said seat and extended therefrom to a surface-contacting position, and shoulders along the sides of said element in contact with said body along the sides of said seat, and means to secure said element against outward displacement.

10. In a suction cleaner agitator, a body formed with an agitating elementseat having outwardly facing shoulders along its sides and above its bottom, a surface-contacting agitating element in said seat and extended therefrom to a surface-contacting position, and body-contacting portions along the sides of said element so formed as to seat on said shoulders, and means to prevent outward displacement of said element from said body.

11. In a suction cleaner agitator, a body formed with an elongated agitating element seat having outwardly and upwardly inclined shoulders at its sides, a removable agitating element seated on said body and extended from within said seat to a surface-contacting position, said element being formed with inclined shoulders to rest upon the shoulders of said seat to support said element, and means to oppose separation of the shoulders on said back and on said seat.

12. A suction cleaner agitator element comprising an elongated body including a base portion, a surface-contacting portion, and shoulders at the sides of said element between the bottom of said base portion and the top of said surfacecontacting pprtion.
